Occupational Health Recommendation - HR

[Googleboxfan]

Hello
Won't go into too much detail but husband has been off sick with workplace bullying. He asked to be moved departments. HR have refused to permanently move him.
Had a Occ Health assessment and GP has recommended he is moved departments in order for him to get better, as suffering high anxiety levels and if returned to same department will never recover.
Does anyone know if HR refuse to move and say he has to stay in same department what would happen?
If Occ Health have advised for him to be moved does HR now have an obligation to agree to this?
Any advice would be gratefully received.
Thanks x

In most organisations when you get to the end of sick pay then that is an automatic trigger to start dismissal processes. Do you mean SSP or the company's sick pay arrangements?

Company sick pay. For example in the NHS dependent on service it may be as long as 6 months full pay, then 6 months half pay. At the end of a year unless there is a strong route and plan for return to work they would generally start considering a dismissal for capability. Not normally for things like cancer etc but fir long term ongoing conditions that mean the staff member is unlikely to return to work
